After my first few visits to towers, I enjoyed the thrill of Rita and even decided it was my favourite at the park. This year, after not visiting for many years, I have noticed how rough it can be, and also how boring the layout is after the initial launch. But above all of that, my main hate for Rita is it's reliability. I think I have experienced over 5 breakdowns on it this year, which just seems a little ridiculous.
I think Rita is next to go. There is little that can be done to improve the experience or the reliability, so it should definitely go before any other major ride.
